Abstract
Self-aligning light source and detector assembly having a sensor support mounted in a predetermined, fixed position, a light source holder mounted in a predetermined, fixed position relative to the sensor support, a sensor mounted in a fixed position on the sensor support, and a lamp assembly removably mounted to the light source holder in a predetermined position defined by mating surfaces which engage each other and seat the lamp assembly in the predetermined position whenever the lamp assembly is installed in the holder.
Claims3
A measuring system for absorbance measurements in a process medium, in particular in a pharmaceutical or biotechnological process, comprising:
- a disposable container in which the process medium is received, the container comprising a container wall, in which a probe head is accomodated, said probe head comprising a first bore for receiving a light source holder and a second bore for receiving a sensor support;
- a light source and detector assembly, comprising the light source holder and said sensor support mounted in a mounting block in a predetermined, fixed position relative to each other, a lamp assembly mounted to said light source holder in a predetermined position and a detector mounted in a fixed position on said sensor support, wherein:
- said light source holder and said sensor support are received in said first and second bore of said probe head respectively, and
- said probe head comprises apertures providing a light beam passageway between said lamp assembly and said detector.
